With the economy the way it its you probably won't be too shocked to learn that at 21, I am still living at home with my two two younger sisters. Mom and Dad's old place is really too small for five people, but my sisters Melanie, 14, and and Tammy, 16, didn't complain too much about sharing their room. I found out why last week.

Mom and Dad were at the movies. I'd had a date, but she phoned and called it off at the last minute. If Melanie and Tammy had known I'd be home so early, they probably would have closed their bedroom door. As it was, however, I had a good view of their nude, sweaty bodies tangled up in a lesbian sixty-nine when I went down the hall.

I watched as Melanie little lifted her sticky face from Tammy's twat. She actually licked her nasty pink lips in front of her own brother before thinking of something to say. "Well, don't just stand there. Climb in and get your share."

"What?", I said incredulously. "I can't believe you said that Mel! I'd tell Mom and Dad, except that it would kill them. I guess it's up to me to give you both a good spanking."

At that, Tammy's juice-smeared face emerged from underneath Melanie's crotch.

"Oooooooh, I'll be in that! I can never get Melanie to spank me as hard as I want." That's when I knew I was really in trouble. Now that their secret was out, my two little sisters wasted no time in yanking me into the bed and peeling off my clothes. To be honest, I wasn't really putting up much of a fight. In fact, I was actually lifting my arms and shifting my weight to help them strip me down. My cock was good and hard. Right or wrong, I couldn't deny that I'd been powerfully aroused by the sight of my sisters licking and sucking each other's hot naked little pussies.

"So, are you going to spank me, big brother?" Tammy wriggled across my bare legs and lifted her firm young up ass a few inches. The invitation was too much to resist. While Melanie maneuvered her crotch under her her sister's face to feed her some more pussy-juice, I took aim at Tammy's tight little butt with my bare hand. A few swats were all it took to get her gorgeously creamy buns nice and red.

"Fuck me up the ass, big brother," Tammy mumbled into Melanie's pussy. I could hardly understand what she was saying. When I did figure it out, I couldn't believe it! My 14-year-old little sister was actually asking me to fuck her in the ass!

Every time I thought I knew these two, they soared to a new height of nasty! "She really likes getting a cock up her ass right after she's been spanked," Melanie confirmed with a shrug. "Me, I like to stick with the basics, lots and lots of tongue and cock."

I slapped some spit on my dick and poked into Tammy's pink, tingling butt from behind while she continued to exercise her tongue on Melanie's juicy twat. I could hardly believe I was actually doing it, skewering my little sister's bunghole with my hard cock while she sucked out my other sister's honey-coated fur pie, but I was! There was no denying the hot, buttery grip of Tammy's tight little asshole on my rock-hard cock.
